Description

TECHNICAL FIELD

[0001] The present application relates to the field of fireproof curtain, in particular to an intelligent wet metallurgical extraction separation section fire extinguishing system. BACKGROUND

[0002] Traditional fireproof curtains mainly rely on a single physical barrier to block fire and heat radiation, although they can prevent the spread of fire to some extent, but at high temperatures, the fire resistance of the curtain itself is limited, and it is difficult to maintain effective isolation for a long time. Once the curtain is damaged by high temperature, its fireproof effect will be greatly reduced and cannot provide continuous protection.

[0003] The currently disclosed Chinese patent CN111764802B is a fireproof curtain door, which comprises a curtain piece, a bottom hook, a rib plate, a top hook and a stopper. The curtain piece is a hollow strip structure, the middle part of the inside of the curtain piece is provided with a rib plate, the upper part of the curtain piece is provided with a top hook, and the lower part of the curtain piece is provided with a bottom hook. The inside of the curtain piece is filled with asbestos, and the left and right sides of the curtain piece are inserted with stoppers; a plurality of curtain pieces form a curtain door, and two adjacent curtain pieces are connected by the top hook on the lower curtain piece hooking on the bottom hook on the upper curtain piece; the fireproof curtain door further comprises a guide piece and a steel pipe, the uppermost curtain piece is connected with a guide piece through a rivet, and the upper part of the guide piece is connected with a steel pipe through a rivet; the fireproof curtain door further comprises a horizontal rib and a tubular motor, the output shaft of the tubular motor is provided with a horizontal rib, and the output shaft of the tubular motor and the horizontal rib are inserted into the right part of the steel pipe; the fireproof curtain door further comprises a bearing seat, a side shaft, a connecting block and a side cover plate, one side cover plate is arranged on the left and right sides, the right end of the tubular motor is fixedly connected to the side cover plate on the right side, the left end of the steel pipe is fixedly connected with a connecting block, the left side of the connecting block is fixedly connected with a side shaft, and the left end of the side shaft is rotatably connected to the bearing seat. The bearing seat is fixedly connected to the side cover plate on the left end.

[0004] According to the above-mentioned patent, the above-mentioned patent connects a plurality of curtain pieces to form a curtain door, and the inside of the curtain piece is filled with asbestos, which makes the curtain door have the effect of resisting fire. However, the curtain has no cooling function and can only rely on asbestos to resist high temperature. This single protection method is prone to cause the curtain to fail prematurely when facing a fierce fire. And due to the impact of the heat wave, the curtain will bear a lot of pressure and be damaged, thus unable to continue to play the isolation effect. Therefore, there is a need for an intelligent wet metallurgical extraction separation section fire extinguishing system that provides more comprehensive fire protection using cooling and buffering mechanisms. SUMMARY

[0005] To address the problems existing in existing technologies, an intelligent fire extinguishing system for the hydrometallurgical extraction and separation section is provided. The system deploys the first and second curtain sheets through a drum to form a multi-layer protection system and create a cooling space. At the same time, the system activates the water curtain generator, steam ejector, cooling pipes and carbon dioxide fire extinguishing robot to quickly lower the temperature, prevent the spread of flames and extinguish the fire.

[0006] To address the problems of the prior art, the present invention provides an intelligent fire extinguishing system for the hydrometallurgical extraction and separation process, comprising a fire hazard robot automatic patrol system, a fire hazard and fire automatic disposal system, and a pollutant collection system during fire disposal. The fire hazard robot automatic patrol system is used to perform infrared camera temperature inspections of the extraction line area, the fire hazard and fire automatic disposal system is used to isolate and extinguish the fire area, and the pollutant collection system during fire disposal is used to collect water generated by fire extinguishing and leaked materials. The fire hazard and fire automatic disposal system includes a track-mounted fire extinguishing robot and a fireproof rolling curtain isolation and fire extinguishing device. The fireproof rolling curtain isolation and fire extinguishing device includes a rolling curtain mechanism applied around the extraction tank of the hydrometallurgical extraction line. The rolling curtain mechanism includes a frame, a first curtain slat, and a second curtain slat. The upper portions of the first curtain slat and the second curtain slat are each fixedly connected to a rotatable drum mounted on the frame, and the lower portions of the first curtain slat and the second curtain slat are each fixedly connected to a movable roller capable of vertical movement on the frame. The frame is provided with a rotary drive for simultaneously driving the two rollers to rotate, causing the first curtain slat and the second curtain slat to be rolled up or drooped and extended.

[0007] Preferably, a sliding portion slidably arranged on a frame is fixedly provided between the ends of the two movable rollers, and a sliding groove for the sliding portion is provided on the frame. A water curtain generator for forming a layer of water film on the surface of the first curtain sheet and a steam ejector for extinguishing fire are provided on the side of the first curtain sheet facing the extraction tank. When the first curtain sheet and the second curtain sheet are both in an unfolded state, a cooling space is formed between the first curtain sheet and the second curtain sheet, and a cooling pipe is provided on the frame for passing cooling gas into the cooling space.

[0008] Preferably, the movable roller of the first curtain sheet is composed of a shaft portion and a sleeve portion, the shaft portion is fixedly connected to the sliding portion, the sleeve portion is rotatably sleeved on the shaft portion, the lower portion of the first curtain sheet is fixedly connected to the sleeve portion, and a torsion spring is fixedly connected between the sleeve portion and the shaft portion for providing a buffering effect when the first curtain sheet is impacted by a heat wave. When the first curtain sheet is impacted by a heat wave, the torsion spring is in a torsion state, so that the pressure exerted on the first curtain sheet is buffered.

[0009] Preferably, a pressure buffer component is provided on the frame and is located between the first curtain sheet and the second curtain sheet to enhance the buffering effect of the first curtain sheet.

[0010] Preferably, the pressure buffer assembly includes a support rod movably arranged between the first curtain sheet and the second curtain sheet and a plurality of elastic buffer members evenly distributed on the support rod. When the first curtain sheet and the second curtain sheet are unfolded or rolled up, the support rod is in a state of moving synchronously and in the same direction as the movable roller, so that the support rod is always between the first curtain sheet and the second curtain sheet.

[0011] Preferably, both ends of the cooling pipe extend toward a sliding part respectively and the cooling pipe is fixedly connected to the sliding part. The axial direction of the cooling pipe is parallel to the axial direction of the movable roller. A plurality of air holes are opened on the top of the cooling pipe along its axial direction. When the movable roller moves to the bottom of the frame, the cooling pipe is at the bottom of the frame at the same time. At this time, the cooling gas ejected from the air holes is in a spraying state that diffuses from bottom to top in the cooling space formed.

[0012] Preferably, one end of the support frame rod is movably connected to the frame, and the other end is movably connected to the cooling pipe fitting. The upper half of the frame has a hinge seat for the end of the support frame rod to be hinged. The sliding sleeve on the cooling pipe fitting is provided with a sliding sleeve and the sliding sleeve has a hinge portion for the end of the support frame rod to be hinged. When the movable roller moves along the slide groove, as the cooling pipe fitting and the sliding sleeve slide together, the support frame rod is in a state of rotation with the hinge seat as the axis.

[0013] Preferably, the elastic buffer is composed of a pressure rod and a buffer spring, the end of the pressure rod is in contact with the inner surface of the first curtain piece, and a rod sleeve for inserting the pressure rod is fixedly provided on the support frame rod. The buffer spring is fixedly arranged between the pressure rod and the rod sleeve. When the first curtain piece is subjected to the impact of a heat wave, the pressure rod is subjected to an extrusion force, so that the buffer spring is in a compressed state.

[0014] Preferably, the end portion of the pressing rod that contacts the inner surface of the first curtain sheet is a round head structure.

[0015] Preferably, the water curtain generator is specifically a tubular structure, which is arranged on the frame and located close to the drum. The axial direction of the water curtain generator is parallel to the axial direction of the drum, and the bottom of the water curtain generator is provided with a flow channel along its axial direction that is in contact with the outer surface of the first curtain sheet.

[0016] Compared with the prior art, the present invention has the following advantages:

[0017] 1. This invention continuously monitors the environment through smoke sensors and patrol robot infrared cameras. Once a fire is detected, the control system immediately activates the emergency program, driving the roller to unfold the first and second curtain slats, providing multi-layer protection and forming a cooling space.

[0018] Depending on the fire situation, CO2 firefighting robots, water curtain generators, cooling pipes, and steam ejectors are activated to rapidly reduce the temperature, prevent the spread of flames, and extinguish the fire. The resulting waste liquid is collected in a firefighting waste liquid collection tank, preventing secondary contamination. This ensures efficient isolation and firefighting, preventing the spread of the fire to adjacent equipment and the surrounding environment.

[0019] The present invention is particularly suitable for scenarios where fire hazards exist in adjacent areas such as hydrometallurgical extraction lines.

[0020] 2. The present invention uses the elastic buffer to work in conjunction with the torsion spring in the sleeve portion to reduce the impact force of the heat wave on the first curtain sheet, significantly enhancing the buffering effect of the first curtain sheet when it is impacted by the heat wave, and reducing excessive deformation or damage caused by the impact.

[0021] The support rod moves synchronously and in the same direction as the movable roller, ensuring that it is always located between the first and second curtain slats. This allows several elastic buffers to support the first curtain slat at multiple points, improving its stability and impact resistance after deployment. This allows the impact force to be evenly absorbed and dispersed, preventing excessive localized force and enhancing the fire isolation effect.

[0022] 3. The present invention not only rapidly reduces the temperature around the first curtain piece by using a cooling pipe to spray gas from bottom to top, but also effectively curbs the spread of fire, thereby significantly enhancing the fire prevention capability.

[0023] As the first and second curtain slats unfold and retract, the cooling tube moves synchronously with the movable roller, maintaining its position between the first and second slats. This ensures that the cooling gas is effectively sprayed into the cooling space. By effectively reducing the temperature, the cooling tube reduces damage to the first curtain slats caused by high temperatures, thereby extending their service life.

[0038] In order to further understand the features, technical means, specific objectives and functions achieved by the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0039] See also Figures 1-9 As shown, an intelligent fire extinguishing system for the extraction and separation section of hydrometallurgy includes an automatic inspection system for fire hazards by robots, an automatic disposal system for fire hazards and fires, and a pollutant collection system during the fire disposal process. A fire hazard robot automatic inspection system is used to conduct infrared camera temperature measurement inspections on the extraction line area; a fire hazard and fire automatic handling system is used to isolate and extinguish the fire area; a pollutant collection system during the fire handling process is used to collect water generated by fire extinguishing and leaked materials. Among them, the fire hazard and fire automatic handling system includes a track-type fire-fighting robot and a fireproof roller shutter isolation fire-extinguishing device. The fireproof roller shutter isolation fire-extinguishing device includes a roller shutter mechanism 2 applied around the extraction tank 1 of the hydrometallurgical extraction line. The roller shutter mechanism 2 includes a frame 21, a first curtain piece 22 and a second curtain piece 23. The upper parts of the first curtain piece 22 and the second curtain piece 23 are fixedly connected to a roller 221 that is rotatable and arranged on the frame 21. The lower parts of the first curtain piece 22 and the second curtain piece 23 are fixedly connected to a movable roller 222 that can move vertically on the frame 21. The frame 21 is provided with a rotary drive for simultaneously driving the two rollers 221 to rotate, causing the first curtain piece 22 and the second curtain piece 23 to be rolled up or drooped and unfolded.

[0040] The rotary drive is not shown in the figure. The fire hazard robot automatic inspection system includes a smoke sensor 11 and an inspection robot infrared camera 12 located above the extraction tank 1. The smoke sensor 11 is fixedly mounted in the center of the fire isolation zone. Above the fire isolation zone, a track is provided for the inspection robot infrared camera 12 and a track-mounted firefighting robot, specifically a carbon dioxide firefighting robot 13 capable of traveling along the track. The pollutant collection system during fire control includes a firefighting waste liquid collection tank 14 located below the extraction tank 1.

[0041] The inspection robot's infrared camera 12 periodically conducts a 360-degree infrared temperature inspection of the mixing motor and the top of the extraction tank 1. If the motor temperature exceeds 60°C, the system reports back to the operator and maintenance personnel for repairs to prevent overheating and fire. If the motor temperature or the temperature of other points on the tank surface exceeds 80°C (the flash point of the solvent kerosene), the system reports back to the operator and maintenance personnel for emergency measures.

[0042] When the infrared camera 12 of the inspection robot senses early signs of fire, it immediately notifies the operator and the carbon dioxide extinguishing robot 13, which quickly rushes to the fire area and, based on the smoke and fire identification system it carries, aims the carbon dioxide nozzles at the flame area while releasing enough carbon dioxide to extinguish the fire. Above each extraction tank 1 in each separate zone, four roller blind mechanisms 2 are installed to form an isolation area. When the carbon dioxide extinguishing robot 13 cannot control the fire, it notifies the fire hazard and automatic fire handling system and the DCS system, which automatically starts the roller blind mechanisms 2. The four roller blind mechanisms 2 are driven simultaneously, and adjacent fireproof areas can share one roller blind mechanism 2 (two can also be installed, each for its own use), ensuring that all roller blind mechanisms 2 can be lowered simultaneously.

[0043] Under normal circumstances, the first and second curtain pieces 22 and 23 of the roller blind mechanism 2 are in a rolled-up state, and the roller 221 is controlled by a rotary drive. The first and second curtain pieces 22 and 23 are rolled up. The smoke sensor 11 and the infrared camera 12 of the inspection robot continuously monitor the extraction tank 1 and its surroundings to ensure that there are no signs of fire.

[0044] When a fire occurs in the extraction tank 1, the smoke sensor 11 and the infrared camera 12 of the inspection robot will immediately detect the fire signal and transmit it to the control system. After receiving the fire signal, the control system starts the emergency program, including starting the rotary drive, water curtain generator 3, steam ejector 4, and carbon dioxide extinguishing robot 13. The control system starts the rotary drive to drive the two rollers 221 to rotate in opposite directions, causing the first and second curtain pieces 22 and 23 to simultaneously drop and unfold.

[0045] Since the extraction tank 1 is surrounded by roller blind mechanisms 2, the fire is isolated and prevented from spreading outward. At the same time, the carbon dioxide extinguishing robot 13 is activated, automatically locates the fire source based on the fire signal and real-time monitoring by the infrared camera 12 of the inspection robot, and sprays carbon dioxide to extinguish the fire. Carbon dioxide can quickly reduce the oxygen concentration at the fire source, extinguish the flame, and prevent the fire from spreading further. During the extinguishing process, the waste liquid is collected in the fire waste collection tank 14 below the extraction tank 1, preventing secondary pollution. After the above series of measures, the fire is effectively controlled and eventually extinguished. After the fire is extinguished, the rotary drive is activated again to roll up the first and second curtain pieces 22 and 23, returning them to the initial state and preparing for the next emergency.

[0046] Referring to Figure 6-Figure 9As shown, a sliding portion 2221 slidably mounted on a frame 21 is fixedly provided between the ends of the two movable rollers 222. A sliding groove for the sliding portion 2221 is provided on the frame 21. A water curtain generator 3 for forming a water film on the surface of the first curtain 22 and a steam ejector 4 for extinguishing fire are provided on the side of the first curtain 22 facing the extraction tank 1. When the first curtain 22 and the second curtain 23 are both in the unfolded state, a cooling space 24 is formed between the first curtain 22 and the second curtain 23. A cooling pipe 241 for passing cooling gas into the cooling space 24 is provided on the frame 21.

[0047] As the roller 221 rotates, the first curtain sheet 22 and the second curtain sheet 23 are gradually unfolded. Under the gravity of the movable roller 222, the sliding part 2221 slides in the sliding groove to ensure that the first curtain sheet 22 and the second curtain sheet 23 are smoothly unfolded.

[0048] When the first and second curtain slats 22, 23 are fully extended, a cooling space 24 is formed between them. The cooling pipe 241 is activated, directing cooling gas into the cooling space 24. The cooling gas flowing through the cooling space 24 further lowers the temperature of the first curtain slats 22 and their surroundings, providing an additional cooling effect. This effectively blocks the transmission of flames and heat radiation, preventing the spread of fire.

[0049] Water curtain generator 3 is simultaneously activated, spraying a water curtain onto the surface of first slat 22, forming a water film. This water curtain rapidly absorbs heat, lowering the temperature of first slat 22 and its surroundings, slowing heat conduction. The water curtain also partially blocks the flame and thermal radiation, protecting first slat 22 from direct flame impact.

[0050] The steam injector 4 is also started at the same time to start injecting steam to dilute the oxygen in the air, inhibit the combustion process, and help control the spread of fire.

[0051] See also Figures 6-10 As shown, the movable roller 222 of the first curtain piece 22 is composed of a shaft portion 2222 and a sleeve portion 2223. The shaft portion 2222 is fixedly connected to the sliding portion 2221, and the sleeve portion 2223 is rotatably sleeved on the shaft portion 2222. The lower portion of the first curtain piece 22 is fixedly connected to the sleeve portion 2223. A torsion spring 223 is fixedly connected between the sleeve portion 2223 and the shaft portion 2222 to provide a buffering effect when the first curtain piece 22 is subjected to a heat wave. When the first curtain piece 22 is subjected to a heat wave, the torsion spring 223 is in a twisted state, so that the pressure on the first curtain piece 22 is buffered.

[0052] A positioning structure capable of fixing the movable roller 222 is provided at the bottom of the frame 21 so that the unfolding of the first curtain sheet 22 and the second curtain sheet 23 remains stable. The positioning structure is not shown in the figure.

[0053] When the first curtain sheet 22 and the second curtain sheet 23 are unfolded simultaneously, the movable roller 222 of the first curtain sheet 22 is directly fixed by the positioning structure, while the movable roller 222 of the second curtain sheet 23 is fixed by the shaft portion 2222 through the positioning structure, and the sleeve portion 2223 is still in a state of being able to rotate relative to the shaft portion 2222.

[0054] When the first curtain piece 22 is impacted by a heat wave, the sleeve portion 2223 is rotatably sleeved on the shaft portion 2222 and, under the action of the torsion spring 223, the sleeve portion 2223 can rotate relative to the shaft portion 2222 by a certain angle. The torsion spring 223 is in a twisted state, helping the first curtain piece 22 to buffer the impact force and reduce excessive deformation or damage caused by the heat wave impact.

[0055] See also Figure 6-Figure 9 As shown, a pressure buffer component 5 is provided on the frame 21 and is located between the first curtain sheet 22 and the second curtain sheet 23 to enhance the buffering effect of the first curtain sheet 22 .

[0056] When the first curtain piece 22 is impacted by a heat wave, the pressure buffer assembly 5 further absorbs the impact energy. The pressure buffer assembly 5 works in conjunction with the torsion spring 223 in the sleeve portion 2223 to reduce the impact force of the heat wave on the first curtain piece 22.

[0057] The buffering effect of the first curtain slats 22 when subjected to heat waves is significantly enhanced, so that the first curtain slats 22 are more stable after being deployed, and the efficient isolation performance of the first curtain slats 22 can be maintained even in the case of a large fire.

[0058] See also Figure 6-Figure 12 As shown, the pressure buffer assembly 5 includes a support rod 51 movably arranged between the first curtain sheet 22 and the second curtain sheet 23 and a plurality of elastic buffer members 52 evenly distributed on the support rod 51. When the first curtain sheet 22 and the second curtain sheet 23 are unfolded or reeled in, the support rod 51 is in a state of synchronous and synchronizing movement with the movable roller 222, so that the support rod 51 is always between the first curtain sheet 22 and the second curtain sheet 23.

[0059] When the first curtain piece 22 and the second curtain piece 23 are gradually unfolded, the support frame rod 51 is also unfolded at the same time.

[0060] When the first curtain piece 22 is impacted by a heat wave, the sleeve portion 2223 can rotate relative to the shaft portion 2222, and the torsion spring 223 is in a twisted state, playing a preliminary buffering effect. At the same time, the elastic buffer member 52 on the support frame rod 51 begins to play a role.

[0061] The elastic buffers 52 are evenly distributed on the support rod 51, ensuring that the entire support rod 51 can evenly absorb and disperse the impact force. When the first curtain sheet 22 is impacted by a heat wave, the elastic buffers 52 will be compressed to further absorb the impact energy.

[0062] See also Figures 6-11 As shown, both ends of the cooling pipe 241 extend toward a sliding portion 2221 respectively and the cooling pipe 241 is fixedly connected to the sliding portion 2221. The axial direction of the cooling pipe 241 is parallel to the axial direction of the movable roller 222. A plurality of air holes 2411 are opened on the top of the cooling pipe 241 along its axial direction. When the movable roller 222 moves to the bottom of the frame 21, the cooling pipe 241 is at the bottom of the frame 21 at the same time. At this time, the cooling gas ejected from the air holes 2411 is in a spraying state that diffuses from bottom to top in the cooling space 24 formed.

[0063] When the movable roller 222 moves to the bottom of the frame 21, the cooling pipe 241 also moves to the bottom of the frame 21. At this time, the air holes 2411 on the cooling pipe 241 begin to spray cooling gas. The cooling gas is ejected from the air holes 2411 from bottom to top, filling the cooling space 24 formed.

[0064] The bottom-up spraying method helps quickly reduce the temperature around the first curtain slats 22, preventing damage to the first curtain slats 22 caused by high temperatures. It evenly covers the entire cooling space 24, ensuring a more uniform temperature distribution. By continuously spraying cooling gas, the spread of fire can be effectively suppressed, improving the overall fire protection performance.

[0065] See also Figure 6-Figure 12 As shown, one end of the support frame rod 51 is movably connected to the frame 21, and the other end is movably connected to the cooling pipe 241. The upper half of the frame 21 has a hinge seat 511 for hinged connection of the end of the support frame rod 51. The sliding sleeve on the cooling pipe 241 is provided with a sliding sleeve 512 and the sliding sleeve 512 has a hinge portion 5121 for hinged connection of the end of the support frame rod 51. When the movable roller 222 moves along the slide groove, as the cooling pipe 241 slides with the sliding sleeve 512, the support frame rod 51 is in a state of rotation with the hinge seat 511 as the axis.

[0066] As the first and second curtains 22 and 23 gradually unfold, the cooling tube 241 moves synchronously. The sliding sleeve 512 on the cooling tube 241 slides along with the movement of the cooling tube 241. The sliding sleeve 512 slides along the cooling tube 241, causing the support frame rod 51 to rotate about the hinge seat 511 as the axis.

[0067] When the movable roller 222 moves to the bottom of the frame 21, the cooling pipe 241 also moves to the bottom position. The support frame rod 51 is finally deployed in the cooling space 24, ensuring that the elastic buffer member 52 is evenly distributed during the deployment of the first curtain slat 22, better absorbing and dispersing the impact force and reducing the situation of excessive local force.

[0068] See also Figure 6-Figure 12 As shown, the elastic buffer member 52 is composed of a pressure rod 521 and a buffer spring 522. The end of the pressure rod 521 contacts the inner surface of the first curtain piece 22. A rod sleeve 5211 for inserting the pressure rod 521 is fixedly provided on the support frame rod 51. The buffer spring 522 is fixedly arranged between the pressure rod 521 and the rod sleeve 5211. When the first curtain piece 22 is impacted by a heat wave, the pressure rod 521 is subjected to an extrusion force, so that the buffer spring 522 is in a compressed state.

[0069] When the first curtain slat 22 is impacted by a heat wave, the resulting pressure acts on it. This pressure is then transferred to the pressure rod 521, which is in contact with its inner surface. The pressure on the pressure rod 521 causes it to move toward the inside of the rod sleeve 5211. The compression of the buffer spring 522 absorbs and disperses some of the impact force.

[0070] When the heat wave weakens or disappears, the buffer spring 522, due to its elastic properties, gradually returns to its unaffected state. The pressure rod 521 then returns to its initial position, maintaining contact with the inner surface of the first curtain slat 22. This effectively resists the heat wave and protects the first curtain slat 22 from damage.

[0071] See also Figure 12 As shown, the end portion of the pressing rod 521 that contacts the inner surface of the first curtain piece 22 is a round head structure.

[0072] The rounded head structure of the pressing rod 521 can reduce the friction between the pressing rod 521 and the inner surface of the first curtain piece 22 , thereby reducing wear between the two and helping to extend the service life of the first curtain piece 22 .

[0073] Compared with a sharp or flat end, a round end can better disperse the stress points, thereby preventing the first curtain piece 22 from being deformed or damaged due to excessive local stress.

[0074] See also Figure 6-Figure 9 and Figure 13 As shown, the water curtain generator 3 is specifically a tubular structure, which is arranged on the frame 21 and located near the drum 221. The axial direction of the water curtain generator 3 is parallel to the axial direction of the drum 221, and the bottom of the water curtain generator 3 is provided with a flow channel 31 along its axial direction that is in contact with the outer surface of the first curtain sheet 22.

[0075] The frame 21 is provided with an adaptive component 32 for ensuring that the flow channel 31 of the water curtain generator 3 always fits the outer surface of the first curtain sheet 22 during the unwinding process.

[0076] The adaptive assembly 32 includes a guide rail 321 and an elastic pull cord 322. The guide rail 321 is fixedly mounted on the frame 21, and the trajectory of the guide rail 321 is perpendicular to the deployment direction of the first curtain slats 22. The end of the water curtain generator 3 is fixedly connected to a movable guide wheel 3211 that slides in the guide rail 321. The guide rail 321 has a fixed guide wheel 3212. The elastic pull cord 322 is a closed-loop structure and is sleeved between the movable guide wheel 3211 and the fixed guide wheel 3212.

[0077] When the first curtain sheet 22 is being rolled up, the thickness of the first curtain sheet 22 on the drum 221 gradually increases, pushing the water curtain generator 3 to move outward along the guide rail 321. At this time, the elastic pull rope 322 is in a gradually stretched state, thereby ensuring that the flow channel 31 and the outer surface of the first curtain sheet 22 are always in contact with each other, and does not hinder the drum 221 from rolling up the first curtain sheet 22.

[0078] As the first curtain sheet 22 is unrolled, the thickness of the first curtain sheet 22 on the drum 221 gradually decreases. At this time, the elastic pull cord 322 gradually returns to a state without external force, pulling the water curtain generator 3 inward along the guide rail 321 while maintaining the fit between the flow channel 31 and the outer surface of the first curtain sheet 22. This improves the water film generation effect on the surface of the first curtain sheet 22 and enhances the fire isolation and water flow fire extinguishing capabilities.

[0079] See also Figure 6-Figure 9 and Figure 13 As shown, the steam ejector 4 has a plurality of nozzles 41 fixedly arranged thereon at equal intervals along the axial direction of the water curtain generator 3 .

[0080] The nozzles 41 are arranged at equal intervals to ensure that the steam is evenly distributed along the entire length of the water curtain generator 3, thereby avoiding the situation where the steam is too concentrated in some areas and insufficient in other areas, thereby improving the overall steam coverage effect.

[0081] Through the evenly distributed nozzles 41, steam can be sprayed more comprehensively toward the fire, forming a stable steam layer, thereby better diluting the oxygen in the air, suppressing the combustion process, and helping to control the spread of the fire.

[0082] The present invention continuously monitors the environment through the smoke sensor 11 and the inspection robot infrared camera 12. Once a fire is detected, the emergency procedure is immediately activated, driving the drum 221 to unfold the first curtain slats 22 and the second curtain slats 23, forming a multi-layer protection and creating a cooling space 24. At the same time, the water curtain generator 3, the steam ejector 4, the cooling pipe 241 and the carbon dioxide fire extinguishing robot 13 are activated to quickly lower the temperature, block the spread of flames and extinguish the fire. As the first curtain slats 22 and the second curtain slats 23 are unfolded, the elastic buffer 52 and the torsion spring 223 in the sleeve portion 2223 work together to significantly reduce the impact force of the heat wave on the first curtain slats 22, improve the stability and impact resistance of the first curtain slats 22 after unfolding, and thus significantly enhance the fire isolation effect.

[0083] The above embodiments merely represent one or more embodiments of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of protection of the present invention. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present invention, and such modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be subject to the appended claims.
